My machine will not `git push`?

Hello,
My code will not push to git for some reason. This is the full output.

$ git remote add origin https://[hidden]@api.glitch.com/[hidden/git
$ git push -u origin master

The repository in your Glitch project is not a bare repository, so you can’t push to master.
